摘要:
为研究地质灾害对国道G345山区路段工程建设的影响,为国道线路设计提供依据,选取地形地貌、岩土体类型、斜坡结构、降水量、河流冲刷程度、地质灾害发育现状6个影响因素,采用模糊综合评判法和信息量法对国道G345镇安金钟至木王林场段公路进行了地质灾害危险性评价,将研究区划分为地质灾害危险性大、中等和小3个区。结果表明:模糊综合评判模型和信息量模型评价结果均与研究区实际情况基本相符,危险性大区和危险性中等区主要分布在路基部分和隧道段。通过与实际情况比较分析,对于地质灾害严重区,模糊综合评判模型优于信息量模型; 对于地质灾害较严重区,信息量模型优于模糊综合评判模型。
Abstract:
Abstract:In order to study the influence of geological hazards on the construction of G345 between Jinzhong Village and Muwang Forest Farm in Zhen'an County and to provide the basis for the design,we selected six influential factors such as landforms,rock soil mass types,slope structures,amount of precipitation,degree of river scouring and development condition of geological hazard.According to the geological hazard analysis based on fuzzy comprehensive evaluation and information model,the study area can be divided into three levels:high,moderate and low.The resultsshow that the evaluation results ofthe two models are basically consistent with the field investigation,and highly-dangered area and moderately-dangered area are mainly distributed in the subgrade section and the tunnel section.Through comparative analyses based on field investigation,it shows that fuzzy comprehensive evaluation model is better than information model in the serious area of geological hazard,and the information model is better than fuzzy comprehensive evaluation model in the moderate area of geological hazard.
